TNEMEC FLUORONAR WITH LUMIFLON

New Coating Technology Provide Architects With Superior Coating Systems

Developed by Asahi Glass in 1982, LUMIFLON®

is the first solvent-soluble

fluoropolymer for coatings that can be cured at room temperature, making it highly suitable

for field application. Since that time, fluororesin coatings, such as, Tnemec FLUORONAR,

based on LUMIFLON® raw materials have been produced and manufacturered around the

world and applied to more than 150,000 architectural structures worldwide.

The primary benefits of FLUORONAR with LUMIFLON® are its superior

durability, weatherability and longevity. Because of the strength of FLUORONAR with

LUMIFLON®

’s® Carbon-Fluorine (C-F) bonds, and its unique chemical structure, the

weatherability can be extended for years. In turn, the fluoropolymer’s durability prevents

corrosion from water, oxygen and chloride. With its superior weatherability,

FLUORONAR with LUMIFLON® ensures a longer life on building exteriors and facades,

resulting in less need for repainting and a substantial decrease in life cycle costs compared

to other coatings on the market today.

In addition to its superior durability, FLUORONAR with LUMIFLON® also offers

architects the ability to use brighter colors and higher gloss than Kynar® PVDF systems.

Kynar® dispersions are milky and cloudy, reducing the maximum gloss to about 40.

FLUORONAR with LUMIFLON® resins are clear, meaning that FLUORONAR with

LUMIFLON® resins have no matting effect, offering gloss values as high as 90. That

means FLUORONAR with LUMIFLON® offers architects the option to specify brighter

and more varied and a broad range of gloss, from satin to high gloss.

FLUORONAR with LUMIFLON® has been used in the United States on building

exteriors and facades for over 12 years. Architects are learning that FLUORONAR with

LUMIFLON® coatings can be used on steel, aluminum, fiberglass, concrete and

polycarbonate for 25 to 30 years without fading, providing weathering and corrosion

protection.

Resins. Pigments. Additives.A coating’s aesthetic performance, or how well it retains color and gloss, is based on three main components—resins, pigments and additives. Fluoropolymer resin is more stable and UV resistant than acrylic or conventional polyurethane resin, but a coating’s ability to retain color also relies heavily on the pigment. Because some pigments resist UV light better than others, the pigment selection for a high-performance coating is essential to ensure color retention after several years of exposure. Fluoronar uses higher-quality pigments that are comprised of materials that resist UV damage, while lower-quality pigments—although they may offer the same color initially—quickly degrade, losing their color over time.

Additives are included in coatings for various reasons. They may offer additional corrosion resistance, help with application characteristics or provide hiding. The types and grades of additives can also impact a coating’s UV stability. Some deteriorate when exposed to sunlight, providing a negative impact on film integrity and color and gloss retention. Higher-quality additives generally resist UV light and prevent a weak-link from establishing within the coating film. Fluoronar uses additives that have been carefully selected to resist UV exposure and enhance coating stability.

A premier finish, Fluoronar contains only the best resins, pigments and additives. It also has brilliant color options, making it perfect for architectural accents such as metal awning, decking, window detailing and sculptures—as well as general broad surface coverage. Although its initial material cost is more than that of traditional coatings, Fluoronar offers exceptional long-term value, making it excellent for landmark projects and areas where maintenance painting is prohibitive.

1. Hoffman Architects chose Series 1072 Fluoronar in standard black for the exterior renovation of the verizon Headquarters Building in new York, nY. Because the renovated sections, located 30 stories in the air, would be extremely costly to repaint every few years, Hoffman Architects selected Fluoronar for durability and long-term performance. 2. Building Conservation Associates (BCA) recommended the art deco metal figures beneath the windows of the 75-year old George Fuller Building in new York, nY, be repainted and protected with Series 1078 Fluoronar Metallic and Series 1076 Fluoronar Clear. The metallic used —Fuller Bronze — was a custom color created to match BCA’s color requirement. 3. When it came time to repaint the turrets at the excalibur Hotel and Casino in Las vegas, veldon Simpson Architect chose Series 1070 Fluoronar for long-term protection and exceptional color and gloss performance. Previously, they had to be repainted every two years with conventional polyurethane due to the intensity of the desert sun. Fluoronar was chosen in bright red, blue and metallic gold to match the casino’s existing colors. 4. neglected for many years, the Georgetown pedestrian bridges were in desperate need of restoration and renovation. Because of its increased corrosion protection and color retention, Tadjer-Cohen-edelson Associates chose Series 1072 Fluoronar in dark bronze to coat the bridges’ inner and outer steel.

INDEPENDENT TEST DATA & STUDIES OF LUMIFLON

Weatherability of LUMIFLON® Coatings

Due to the chemical nature of the carbon-fluorine bonds found in LUMIFLON® resins, and

the regularly alternating FEVE structure, LUMIFLON® offers weatherability far exceeding

that available with competitive resins. In both accelerated weathering and natural

weathering tests, LUMIFLON® resins yields better color and gloss retention compared to

acrylic and polyester urethanes, Kynar® PVDF resins, and siloxanes.

QUV-A Test Results

Chemical Resistance of LUMIFLON® Coatings

The Fluoropolymer segments of LUMIFLON® resins also impart excellent chemical resistance.

Shown below are photographs of a LUMIFLON® based coating and an acrylic coating after

exposure to sulfuric acid in an accelerated test. Note that the LUMIFLON® coating is unaffected by

exposure to the acid, while the acrylic urethane is porous, and swollen, indicating attack by the

acid.



LUMIFLON® resins also impart corrosion resistance to coatings. They do so by reducing the

transmission of corrosion initiators like water, oxygen, and chloride. This is due to the extreme

weatherability of LUMIFLON® resins. The photographs below show a LUMIFLON

® based coating

on steel panels after 16 years of exposure on a platform in Sugura Bay in Japan. These are severe

conditions in a humid marine environment.

This figure shows a photograph of the coating system applied on the steel coupon. From the left, the

layers are the LUMIFLON® topcoat, epoxy mid-coat, zinc rich primer, and the steel substrate. Note

that the LUMIFLON® topcoat is whole, without pinholes or damage that would allow penetration

of corrosion intiators.



This figure shows the electron Dispersive x-ray scan (EDX) of the coating system. The

blue at the left is chloride ion on the surface of the LUMIFLON® coating. The green is the

epoxy and the red is the metal substrate. Note that no chloride can be seen on the surface of

the steel. This means that corrosion has not been initiated, even after 16 years.

This photograph shows the zinc rich primer. The right side shows the initial appearance of the

primer, prior to 16 years of exposure on the platform, while the left side shows the zinc rich primer

after exposure. Note that the zinc retains its globular appearance, indicating that corrosion of the

primer has not occurred.



Oxygen Permeability of LUMIFLON® Based Coatings

Oxygen is a potential corrosion initiator, like water and chloride. The data in the table below shows

first, that the permeability of LUMIFLON® based coatings is an order of magnitude lower than that

of acrylic urethanes, and second, that this permeability does not change even after 5,000 hours of

exposure in the Sunshine Weatherometer. Even after extensive weathering, the LUMIFLON® based

coating reduces the permeation of oxygen. In contrast, the acrylic urethane is destroyed after less

than 2,000 hours of accelerated weathering. LUMIFLON® based coatings can therefore be used in

industrial coating systems to maintain both the appearance and the anti-corrosion properties of the

topcoat.

Electrochemcal Impedance Spectroscopy Results

Electrochemical impedance spectroscopy (EIS) can be used to measure the corrosion resistance of

coatings. EIS involves setting up a corrosion cell using a coated panel exposed to a salt solution,

then sending an alternating current between the electrodes. The impedance at constant frequency is

then measured. Results of the test are shown in the figure below. Impedance is measured at time 0,

after 1,000 hours of exposure in a Weatherometer, then after exposure in the ASTM B-117 salt fog

test. The smaller the slope of the resulting line, the higher the corrosion resistance of the coating.

Results show that LUMIFLON® based coatings will retain anti-corrosive properties about 5 times

longer than will an acrylic urethane

When the roofing on one of the office buildings at the Fair Oaks Corporate Center site in Fairfax, Virginia, started showing its age, project engineers kept costs from going through the roof by specifying a field-applied fluoropolymer coating system from Tnemec. “The aged roof showed about 25 percent severe rusting and pitting after 20 years,” recalled Tnemec coating consultant Todd Guntner. “We were able to recoat it at half the cost of replacement.”

Specifications called for the roof structure to be prepared in accordance with SSPC-SP7/nACe no. 4 Brush-Off Blast Cleaning and spot-primed with Series 135 Chembuild, a modified polyamidoamine epoxy for marginally prepared rusty steel and tightly adhering old coatings. The specified primer coat was Series 66 Hi-Build epoxoline, a polyamide epoxy, applied by brush and roller, followed by a finish coat of Series 1072 Fluoronar, a high-solids fluoropolymer coating that offers an ultra-durable finish with outstanding color and gloss retention.

In order to demonstrate the surface preparation, method of application and performance of the coating system, a test patch was prepared on a section of the roof structure and allowed to weather over a six-month period. “We did the surface preparation, applied the entire coating system and left it to weather through freeze-thaw cycles and changes in weather,” Guntner noted. “Then we performed adhesion testing on the mock-up in accordance with ASTM D 3359, Methods A and B.”

The ASTM D 3359 standard covers procedures for assessing the adhesion of coating films to metallic substrates by applying and removing pressure-sensitive tape over cuts made in the film. Results of the adhesion testing were added to proprietary test data on Fluoronar, as well as international research on color and gloss retention of fluoropolymer coatings spanning more than 25 years, which Guntner provided to the owner. “The extensive test data was the clincher,” Guntner noted. “The project engineer had not seen an air-cured fluoropolymer system that would provide the overall performance of the original roof, including color stability and corrosion resistance.”

At 60 percent solids, Fluoronar offered adequate and consistent film thicknesses when applied by brush and roller in the same copper green patina as the building’s original roof. “Between the primers and finish coat, a total of 600 gallons of material were needed to complete the project,” Guntner estimated. And after more than seven years of weathering, Guntner reported that everything about the project continued to remain “thumbs up.”

When Westat, Inc. expanded its headquarters facility in 2009, two Tnemec products turned out to be just what the owners needed to tie the new addition into the old. Westat is an organization that offers survey and statistical research services to agencies in the U.S. government, as well as businesses, foundation and state and local governments. Some of their research areas include education, social services, housing, energy, science and technology, transportation, and environmental protection.

As the organization continued to expand the number of projects and staff working at its Rockville, Maryland headquarters, a building expansion was needed. The expansion project was completed in 2009. During the expansion, Westat added a 50,000 square foot addition that included new metal roofs. The owner had originally planned on replacing the roofs on the existing building to match the roofs of the new addition, but the approximate $1 million cost of replacement caused the owners of Westat to consider a high-performance coating as an alternative.

The coatings applicator heard that the owner was looking for a high performance coating for the existing roof that would also match the newly installed section. According to Tnemec coating consultant Todd Guntner, “The applicator immediately thought of Tnemec as the company who could meet this requirement.” The applicator contacted Guntner and they developed a system that would provide low maintenance and high performance as well as match the newly installed roofs on the addition.

For the roofs, a system utilizing Series 135 Chembuild, a high-build epoxy with superior wetting for marginally prepared rusty steel and self-priming characteristics, followed by a topcoat of Series 1072 Fluoronar, a high-solids fluoropolymer coating that provides an ultra-durable finish with outstanding color and gloss retention, was the best solution for extended protection and color stability.

The applicator high-pressure water jetted the metal roofs in accordance with SSPC-SP12/nACe no. 5. The roofs then received a coat of Series 135. In order to get the existing roofs to match the copper green patina of the new roofs, Tnemec’s color lab created an exact color match. The color-matched topcoat of Series 1072 was then roller-applied at two to three mils DFT. Once applied, the owner was pleased to have chosen coatings that allowed the new roofs to match the original roofs while also providing outstanding color and gloss retention.

Anyone who has been tickled pink, green with envy, or had the blues understands the affect color can have on emotions, so it’s understandable why the CNA Center in Chicago is considered a “hot” property with its red exterior featuring a fluoropolymer coating system from Tnemec. “Whenever you see the Chicago skyline, there’s this lone red building,” according to Tnemec coating consultant Chris Wascher. “From a color perspec-tive, it’s one of a kind.”

The building’s owner wanted to select a coating system that offered the best available life expectancy, so mock-ups of different products were left on the building and evaluated over several months. “They wanted to compare the various coating systems after being exposed to a year’s worth of freeze/thaw cycles,” Wascher noted. “The mockups were evaluated for aesthetics, as well as adhesion, and the coating system that best kept its gloss and color was the Tnemec system with Series 1072 Fluoronar as the finish coat.”

The project was completed in two phases. The first phase consisted of overcoating the exterior steel substrate on the top 42 stories of the 44-story high-rise, as well as aluminum and galvanized louvers located mid-way up the building and on its top two levels. Surface preparation on steel substrates in the first phase was in accordance with SSPC-SP2 Hand Tool Cleaning or SSPC-SP3 Power Tool Cleaning. Existing paint on the aluminum was removed using an environmentally-friendly paint stripper. Exterior steel in phase one was spot-primed with Series 135 Chembuild, a modified polyamidoamine epoxy, followed by an intermediate coat of Series 73 Endura-Shield, an aliphatic acrylic polyurethane. The finish coat was Series 1072 Fluoronar, a high-solids fluoropolymer, in the custom color “CNA Red.” Aluminum and galvanized metal substrates were primed with Chembuild and finished with Fluoronar.

The second phase involved removing all exterior coatings from the building’s lower two levels down to bare steel in accordance with SSPC-SP6/NACE No. 3 Commercial Blast Cleaning. “Rather than just overcoating these areas, they wanted to start from scratch,” Wascher acknowledged. The prime coat used on phase two exterior steel was Series 90-97 Tneme-Zinc, a zinc-rich, aromatic urethane, followed by an intermediate coat of Chembuild and a finish coat of Fluoronar in CNA Red.

Overall, more than 2,300 gallons of coatings were required for the 1.3 million square foot red tower, which was built in 1972. “The ease of application and quick cure times for the coatings made it possible for the applicators to maximize their time,” Wascher added. “They absolutely loved the way it looked.”

When a long-lasting protective coating system was required for a new steel and glass skywalk at Duquesne University, project engineers moved fluoropolymer technology from Tnemec to the head of the class. “The decision was a no brainer,” according to Tnemec coating consultant Shawn Malarik. “The project called for a fluoropolymer material that could be brush-and-roller applied to the pedestrian bridge, which arches 65 feet above a busy road on the Duquesne campus. Long-term color and gloss retention was another key requirement.”

The eight-story, glass-enclosed skywalk features a steel superstructure, contemporary arch frame design, metal roofing and an aluminum window wall system. The bridge links the center of the campus to the $30 million Power Center, a recreational facility housing a two-story book store, juice bar, restaurant, two gyms, classrooms, fitness facilities and a ballroom.

All exposed steel was prepared in accordance with SSPC-SP6/nACe no. 3 Commercial Blast Cleaning prior to receiving a shop-applied prime coat of Series 90-97 Tneme-Zinc, a moisture-cured, zinc-rich aromatic urethane with excellent corrosion resistance. nearly 90 gallons of Tneme-Zinc were required for the project.

next, an intermediate coat of Series 1075 endura-Shield II, an aliphatic acrylic polyurethane was brush-and- roller applied in the field. A finish coat of Series 1072 Fluoronar, a satin finish, high-solids fluoropolymer completed the coating system. Approximately 40 gallons of endura-Shield and 40 gallons of Fluoronar were used on the project. The same three-coat system was also used on an architectural sunshade located adjacent to the university’s student center. “That project came about as a direct result of the work on the skywalk,” Malarik noted.

The bridge’s galvanized deck was chemically treated prior to receiving two coats of Series 30 Spra-Saf en, a direct-to-metal hydrophobic acrylic polymer. Spra-Saf en provides early flash-rust resistance, as well as long-term corrosion protection.

“Another Tnemec coating system was used on a parking garage connected to the Duquesne student center. That project used a coat of Series 1 Omnithane, a single-component, moisture-cured resin containing mica-ceous iron oxide and zinc; an intermediate coat of Series n69 Hi-Build epoxoline II, a polyamidoamine epoxy; and a finish coat of Series 73 endura-Shield, a semi-gloss aliphatic acrylic polyurethane,” reports Malarik.

With more than 10,000 students, Duquesne is consistently ranked among the nation’s top Catholic universi-ties for its award-winning faculty and 130-year tradition of academic excellence.

Margaret Flinner, AIA, architectural director in the Washington, D.C. office of the world-class architectural firm of ellerbe Becket (eB), is the proj-ect designer of the 71,000-square-foot Sports & Fitness Facility on the law school campus of Georgetown University. Formally dedicated in October 2004, the new building contains a swimming pool on the lower level, restaurant and student lounge on the first floor, fitness center and exercise rooms on the second level, topped off by a gymnasium and racquet ball courts on the third floor.

Specializing in sports and athletic venues, Flinner reports to the eB Washington, D.C. office, which is the hub for eB’s world-wide higher education recreation center marketing and design.

“Because our sports venues showcase lots of exposed, structural steel, we have been specify-ing Tnemec high-performance coatings for years,” Flinner said. “We appreciate the fact that Tnemec coatings contribute to the durability, quality and clean, beautiful lines of our athletic venues.”

Working closely with Tnemec coating consultant Todd Guntner, Flinner specifically wanted the look of Tnemec’s Series 1078 Fluoronar Metallic to provide color and gloss for the exterior

“tree-like” support columns. “Tnemec’s coatings beautifully complement the striking, structural steel trusses which support the roof and penetrate the full glass curtain wall, bringing profuse light to all floors of the Center.” Flinner selected Series 1077 enduralume — another member of the Tnemec Premier Finishes family — in a matching grey color to bring the same look and feel indoors.

“We completed phase three of a five phase renovation of the historic Payne Whitney Gym at Yale University, new Haven, Conn.,” Flinner said. “The next phase, the natatorium, to include a 50-meter pool and diving facility, will most certainly feature another Tnemec high-performance coating system. As with the Georgetown Law Center Sports & Fitness Facility, Tnemec will be an integral component of our design.”

For the exterior curtain wall of the new Sports & Fitness Facility at the Georgetown University Law Center, ellerbe Becket selected Tnemec coating systems because “we always try and use Tnemec coatings on our sports centers.”


Updating the two bridges connecting canal-side offices to the fashionable Georgetown Park Mall posed a host of difficult challenges for the nPS: remove years of paint and rust; prevent the blast medium from falling into the waters of the C&O Canal; keep the bridges open at all times to the daily, heavy pedestrian traffic; keep noise levels to a minimum (this prevented heavy equipment — compressors, dust collectors, precipitators, sand blasters — on site and allowed only one small barge in the canal) and deliver a finish that would last for a decade and perfectly match the special nPS brown.

Working closely with United Coatings, Tnemec coating consultant Todd Guntner developed creative solutions to meet all these demands. The 16,000 square feet of previously painted steel had to be fully stripped of the badly deteriorated coating. The contracting team chose to clean to bare metal per SSPC-SP11 guidelines, leaving a one mil surface profile on the steel. To achieve this method of cleaning, the crew used needle-guns and rotor-piners to remove the rust and old paint, as sandblasting was out of the question. Laboring from 7:00 a.m. to 4:00 p.m. in this confined space (5 feet high by 8 feet wide), workers prepared the 80 feet by 3 feet steel beams down to bare metal. To prevent the debris from falling into the Canal, United Coatings built a unique containment structure of wood and plastic tarp around both bridges. Supported by cables, this house of insulated plywood (for noise protection) required the approval of a structural engineer.

For the prime coat, Guntner specified Series 594 Omnithane, a MIO/zinc filled urethane applied at 2.5 to 3.5 mils DFT. For the intermediate coat, Series 27 F.C. Typoxy, a polyamide epoxy, was applied at 3.0 to 5.0 mils DFT. And for the topcoat, Series 1072 Fluoronar, a fluoropolymer specially created to perfectly match the nPS brown color, was applied at 2.0 to 3.0 mils DFT.

“What I learned from this experience is to never say never. It is when the barriers and restrictions appear insurmountable that the greatest opportunity appears! In this case it was a golden opportunity to win the contractor’s trust and give the owner a system, under budget, that will last for years and years,” Guntner says.

When the largest cable-supported domed football stadium in the world required a new color scheme for its exterior, the project called for a well-executed game plan by the project management company, the architect, general contractor and a team of coating professionals.

Coating the exterior of the Georgia Dome presented a challenge given the stadium’s close proximity to moving traffic, nearby parking and office buildings. In order to avoid damage from overspray, all coatings had to be applied by roller. The exterior skin of the dome consists of architectural concrete masonry units (CMUs) to a height of 12 feet, flat metal panels up to the low roof level at 97 feet and corrugated panels from the lower roof to the compression ring 55 feet above. The embossed metal had a textured galvanized surface originally finished with a Polyvinylidene Fluoride (PVDF) coil-coating. Working from 40-foot-wide stages, coating crews prepared both coated and uncoated substrates by washing them with a pre-paint cleaning chemical at a pressure of 3,000 psi and a temperature of 180 degrees F.

Metal panels were primed with Series 66 Hi-Build epoxoline, a polyamide epoxy primer, followed by a topcoat of Series 1071 Fluoronar, a high-solids fluoropolymer polyurethane. A single coat of Fluoronar was specified, except on red panels where two coats were applied. Concrete surfaces received two coats of Series 156 enviro-Crete, a breathable waterborne acrylate.

An ultra-durable finish, Fluoronar was chosen for its user-friendly application characteristics, outstand-ing color and gloss retention, and strong adhesion to aged coil-applied coatings. “We experienced no problems with this product even when a thunderstorm appeared and rained on a freshly coated surface. It was easy to apply, which saved us a lot of headaches,” recalled Charles Wagner, project estimator with Specialty Finishes, Inc., the project’s coating contractor.

Jeff Wierenga, AIA, project architect with the firm of Thompson, Ventulett, Stainback and Associates (TVS) acknowledged, “It was a very smooth-running operation from all sides and we were really pleased with how it turned out.”

As one of the most visited destinations in Maryland, the national Aquarium in Baltimore (nAIB) has kept its interior and exterior structures shipshape for more than a quarter century using the latest coating systems available from Tnemec. “From its beginning, the national Aquarium has been will-ing to use new technology from Tnemec to achieve and maintain long-lasting aesthetic performance,” according to Tnemec coating consultant Todd Guntner.

In 2004, a coating system featuring an advanced fluoropolymer topcoat was used on interior and exterior concrete as part of a 65,000-square-foot expansion. The surface was brush-off blast-cleaned in accordance with SSPC-SP13/nACe no. 6, followed by a prime coat of Series n69 Hi-Build epoxoline II, a polyamidoamine epoxy. A coat of Series 1075 endura-Shield II, a semi-gloss acrylic polyurethane, and Series 1071 Fluoronar, an air-dried fluoropolymer, completed the coating system.

“Fluoronar was chosen for its resistance to ultraviolet light and its long-term performance,” Guntner explained. “In addition, the Aquarium is located right in the harbor, so salt water was an issue, too.”

Prior to the introduction of Fluoronar, the same primer and intermediate coatings were used for concrete along with a topcoat of Series 76 endura-Clear, a high-gloss urethane, to maintain the bright, nautical color scheme used at the Aquarium. “eventually, when the clear coat needs repainting, the Aquarium intends to use Fluoronar,” Guntner said.

Both interior and exterior steel at the nAIB was commercially blast cleaned in accordance with SSPC-SP6/nACe 3 and shop-primed with Series 90-97 Tneme-Zinc, a zinc-rich, moisture-cured urethane. Steel inside the Aquarium’s atriums received an intermediate coat of Series 66 Hi-Build epoxoline, a polyamide epoxy, and a finish coat of Series 73 endura-Shield, an aliphatic acrylic polyurethane.

“We’ve never had to retouch any coating on the atrium steel,” Guntner noted. On exterior steel, an intermediate coat of Series n69 Hi-Build epoxoline II, a polyamidoamine epoxy, was followed by a coat of endura-Shield II and a finish coat of endura-Clear. These applications included a glass curtain wall, handrails, an outdoor pedestrian bridge and artwork resembling a nautical mast.

“Over the years, through expansions and renovations, thousands of gallons of Tnemec coatings have been used at the national Aquarium,” added Guntner.

Opened on August 8, 1981, the nAIB has an annual attendance of 1.6 million visitors.

Not only does the Washington Metropolitan Area Transit Authority operate the second largest rail transit system and the fifth largest bus network in the United States, it also transports more than a third of the federal government to work and millions of other people to the nation’s capitol. Construction of the Metrorail system began in 1969, with the first phase beginning operation in 1976. The final leg of the original 103-mile rail network was completed in early 2001. Today, there are 86 Metro stations in service within a 106.3 mile network.

In September 2002, the WMATA board of directors awarded a $92.8 million contract for construction of the Largo Town Center station and 2,100-space garage along with the Morgan Boulevard station and its 596-space parking lot. Late in 2004, the Blue Line Extension and the two new stations - Morgan Boulevard and Largo Town Center - opened on the east end of the Blue Line. This marked the first construction beyond Metro’s original 103-mile planned system and the first Metrorail service beyond the Capital Beltway in Prince George’s County, Maryland.

When choosing coating systems to protect the stations’ platform areas, cost and durability were of utmost importance to WMATA. Series 1071 Fluoronar and Series 1075 Endura-Shield II were chosen because they are low-maintenance, highly-corrosion resistant topcoats that provide long-term color and gloss retention. Guntner reports, “Tnemec coating systems were one of the few items not value-engi-neered on this project because the owner really stressed the importance of low maintenance for the coatings due to the limited maintenance budget.”

Following commercial blast cleaning in accordance with SSPC-SP6/NACE No. 3, the exposed steel struc-ture and canopy received a shop-applied coat of Series 90-97 Tnemec-Zinc, a zinc-rich, moisture-cured urethane primer, followed by field-applied coats of Series 1075 Endura-Shield II, a semi-gloss acrylic polyurethane, and Series 1071 Fluoronar, a semi-gloss fluoropolymer.

The galvanized decking was prepared by abrasive blast cleaning, followed by a shop-applied prime coat of Series 161 Tneme-Fascure, a polyamide epoxy. A second coat of Series 161 was then applied in the field and topcoated with Series 1071 Fluoronar. An air-dried fluoropolymer, Series 1071 provides an ultra-durable finish and outstanding color and gloss retention even in the most severe exposures.

Tnemec filled the Metro’s request for custom colors and created Wickham Gray for the Morgan station and Chantilly Lace for both stations. According to Tnemec coating consultant Todd Guntner, WMATA is thrilled with the products’ performance to date.
